So I got an account on Darwin Dating.

Here's a brief description of what it's like. It contains much more attractive women than okcupid. A few are quite average, so I'm not sure how they got there, but everyone is doable, and most are very hot.
Most women have nothing except one photo, or a few photos + a few sentences in profile.
There seems to be a hard limit of 4 messages / day (not even 4 people, 4 messages), what's unbelievably annoying. You're not even told that you're over the limit until you try to send a message and get and error.
I don't think there are any spammers - either bots or people.

So far I sent 4 messages, and got 1 reply, a conversation I cannot continue until tomorrow.

So anybody had much success with Darwin Dating?
